'.SCRAPING MACHINES.

175,772. dated Aprnn, 187e; application ined April 29, 1875.

To all whom it may concern:

Be it known that I, NEWMAN SILVER- THORN, of' the village ot' Summerville, in the county of Peel, in the Provincefof Ontario, Canada, have invented an improved machine designed for the purpose ot' economiaing manual labor in the scraping or cleaning of hogs, ot' which the following is` a specification:

This invention consists in an arrangement of straight scrapers affixed horizontally to endless belts passing' around four drums (held within a suitably-constructed frame) upon shafts or spindles made to revolve by the most convenient mechanical power, the whole machine being so arranged and operated, as hereafter specified, that the body of the hogs rest upon the traveling scrapers, which, in passing over the surface ot' the body, effectually remove the hair, Ste., from the hog, as desired.

Figure l represents a longitudinal section. Fig. 2 represents a cross-section through A B. scraperholder with scraper and scrapercleaner attached. Fig. 4.- is a detail plan ot' scraper-holder with scraper and scrape-cleaner attached. Fig. 5 is a detail sectional plan ot' scraper-holder with scraper and scraper-cleaner attached. Fig. 6 is an end View ot' scraperholder with scraper and scraper-cleaner attached.

A is the frame, made ol' any material'and design suitable for the purpose ot the machine. B is the driving-shaft, and (l the carA rying-shaft. D D are the drums, with teeth d placed in them, as shown. E are the endless belts or chains passing around these drums, and upon which the scraper-holders F are secured. yTo these holders the Scrapers G are bolted or otherwise fastened. H are the scraper-cleaners, held loosely within the clips h. 'Ihe frame A is placed on an inclination immediately next to the platform at the end of the scalding-vat. When the hog is elevated from the vat it rests on the platform referred to till the hooi; I is inserted through its lower jaw. rI his hook is attached, by a short swivel-chain, K, to the sliding bar J, as

' shown; ora long chain or rope pivoted at the farther end might be substituted for the said ig. 3 is a detail sectional end view ot" Ishort swivel-chain; or, again, an open hook sliding on the bar might answer the purpose equally well. When the hog is hooked, as described, the tip of its lower jaw should not pass beyond the upper edge ot' the plate L. In this position the hog is rolled by the operator onto the traveling Scrapers, which, when in motion, pass rapidly by the animal and pretty eft'ectually scrape it while it is being rolledacross'the machine by the operator. The inclination ot' the scrapers given by that of the frame assists the operator in rolling the hog across the machine. The notches gcut in the scrapers G are for lessening the friction on the prominent parts of the animals limbs. The scrapers G shall be distributed in such numbers on the endless belt that from the weight ot' the hog resting'upor'. them the same shall be suflcient, while the machine is in motion, to remove the hair, Ste., from the body of the hog.

On each side ot' the machine a segment, M, is placed, for the purpose ot' supporting the belts E, as shown. The hams audshoulders of the hog` tall on either side ot' the segment M, while the body part between them rests on those Scrapers supported by the said segments. By this arrangement 'all portions of the hog is reached, and no undue pressure is experienced at any particular point.

When the machine is in motion it is driven in the direction indicated by the arrow; it follows, then, that as each scraper performs its so its cleaner H falls by gravitation toward ythe cutting-edge ot' the scraper G, passing the said edge and carrying any hair, &c., which may have adhered. While the machine is in motion the Scrapers G, after passing over the drum D', as described, continue, and in succession come in contact with the teeth O of.' the ratchet-rack N, as shown in Fig. 1. By this action the cleaners H, which, in traveling over the drinn 1)', fall past the cuttingsaid edge in passing over' each tooth O, falling again between each ofthe said teeth, passing and repassing the scraper G. In this manner the cleaners eft'ectually perform the service required ot' them, and by the time they reach the last vtooth O will probably be perduty it passes over the drum D', and in doing .Y

edge of the scraper G, are raised clear of the rack N, having teeth O, substantially as speciiied, for the purposes set forth.

3. In combination with the iiexible endless belts E, provided with scraping` and scrapercleaning devices, as described, the segments M for adapting the belts to the shape of the carcass, substantially as and for the purposes described.
